Leak test

Is your connection really protected?

This page checks what any website can see about you right now: your public addresses, how your DNS lookups behave, and whether your browser gives away local network addresses. Nothing is stored.

Checking your connection…

Looking up your public addresses and testing your browser.

IPv4 address

The address websites see when they reach you over IPv4.

Checking…

IPv6 address

Many connections also have an IPv6 address. A VPN that only covers IPv4 leaks it.

Checking…

DNS lookup

Who answers when your device asks where a website lives.

Checking…

WebRTC

Video-call features in browsers can reveal your local network addresses to any site.

What “protected” means

Both your IPv4 and IPv6 addresses belong to CloudTunnel servers. Websites, trackers and your ISP see our server address instead of your own.

What we keep

Nothing. The lookups run in your browser and our server answers with what it sees; no result is stored or tied to an account.

Country

The country is derived from your connecting address when available.

Not protected yet?

Install CloudTunnel, connect, and run this test again. Both your IPv4 and IPv6 traffic should then exit through our servers.
